The primary objective of Anuradhapura North Water Supply Project Phase 1 is to ensure the provision of safe drinking water to the residents of the Rambewa and Medawachchiya DS divisions in the Anuradhapura district, an area where Chronic Kidney Disease (CKDu) is highly prevalent. Approximately 115,900 people in the region will benefit from the project, which includes the establishment of approximately 25,000 new house connections.

This project involves the creation of a water supply infrastructure, which encompasses a 9,400m3/d water treatment plant, three ground reservoirs with capacities of 1,500m3, 1,000m3, and 500m3, and four elevated water towers with capacities of 2,000m3, 1,000m3, 750m3, and 250m3. It also incorporates supply and laying of 89km of HDPE transmission main pipelines, 163km of HDPE distribution main pipelines, a 330km uPVC distribution sub-system, along with the construction of office buildings, quarters, and the implementation of mechanical and electrical works.

The project is structured into seven contract packages, denoted as Lot A, Lot B, Lot C1, Lot C2, Lot C3, Lot D1, and Lot D2. Lot A encompasses the water treatment plant and all related structures, including mechanical and electrical works. Lot B is responsible for the installation of transmission and distribution main pipelines, while Lot C focuses on the uPVC distribution sub-system. Lot D is allocated for the supply of operation and maintenance equipment and vehicles.

The project is funded by Japan International Cooperation Agency (JICA) and Government of Sri Lanka. JICA has provided JPY 5,166 million, while the Government of Sri Lanka has contributed LKR 2,789 million, in accordance with the Loan Agreement No: SL-P 110 signed between Japan International Cooperation Agency and Government of Sri Lanka on 14th March 2013.

The project is now almost completed with a 99.1% of physical progress. The all construction works have been handed over to NWSDB and operation of this scheme has already commenced by Operation and Maintenance section of NWSDB. Up to 31.07.2024, No. 3721 of new house connections have been given.
